Global diversity of polychaetes (Polychaeta; Annelida) in freshwater

  title={Global diversity of polychaetes (Polychaeta; Annelida) in freshwater},
  author={Christopher J. Glasby and Tarmo Timm},
A literature review of Polychaeta (Annelida) including Aphanoneura (the oligochaete-like Aeolosomatidae and Potamodrilidae), living in freshwater yielded 168 species, 70 genera and 24 families representing all of the major polychaete clades, but less than 2% of all species. The best-represented families were, in order, Nereididae, Aeolosomatidae, Sabellidae, Spionidae and Histriobdellidae. Fourteen families were represented by a single species and genus. Regions supporting the highest diversity… 
The Current State of Eunicida (Annelida) Systematics and Biodiversity
This study analyzes the current state of knowledge on extant Eunicida systematics, morphology, feeding, life history, habitat, ecology, distribution patterns, local diversity and exploitation and integrates new methodologies for morphological and molecular study.
Stygobiont polychaetes: notes on the morphology and the origins of groundwater Namanereis (Annelida: Nereididae: Namanereidinae), with a description of two new species
It is suggested that the groundwater polychaetes of this genus might not have entered groundwater from freshwater/anchialine habitats during a single colonization event, as previously suggested, but at different times.
Morphological distinction between estuarine polychaetes: Laeonereis culveri and L. nota (Phyllodocida: Nereididae).
It is indicated that L. culveri and L. nota are different species and that the latter is found in Chetumal Bay, in the Northwestern Caribbean Sea.
Description of a new species of Namalycastis (Annelida: Nereididae: Namanereidinae) from the Brazilian coast with a phylogeny of the genus.
The authors' results suggest that Namalycastis caetensis is closely related to N. geayi and N. fauveli, and the existence of poorly-characterized species limits the understanding of Namanereidinae relationships.
Catalogue of non-marine Polychaeta (Annelida) of the World
An annotated checklist and bibliography of 197 species (representing 78 genera and 26 families) of non-marine polychaetes of the world is presented, including synonymies, information on ecology,
Evolution of the unique freshwater cave‐dwelling tube worm Marifugia cavatica (Annelida: Serpulidae)
Phylogenetic analysis of nuclear rDNA 18S and 28S sequences using maximum parsimony, maximum likelihood and Bayesian analyses places Marifugia as a sister group to a clade of brackish‐water Ficopomatus species, and appears to have taken place once in the evolutionary history of Serpulidae.
Current status of annelid phylogeny
The new annelids phylogeny highlights the variability and lability of annelid body plans, and many instances of simplifications of body plan as adaptations to new life styles can be found.
The troglomorphic adaptations of Namanereidinae (Annelida, Nereididae) revisited, including a redescription of Namanereis cavernicola (Solís-Weiss & Espinasa, 1991), and a new Caribbean species of Namanereis Chamberlin, 1919
A new species belonging to the stygobiont Namanereis group is described here; it shares the common morphological characters of absence of eyes and pigmentation, bi%d jaws, elongation of chaetae and cirri, which have been recently regarded as troglomorphies.
Progress and perspectives in the discovery of polychaete worms (Annelida) of the world
The present study reviewed available data in the World Register of Marine Species, and found that 11,456 valid species of Recent polychaetes (1417 genera, 85 families) have been named by 835 first authors since 1758, and suggested that it has been getting more difficult to find new polychaete species.


The Namanereidinae (Polychaeta: Nereididae). Part 1, Taxonomy and Phylogeny
Phylogenetic results indicate that in both Namalycastis and Namanereis there is a preference for freshwater habitats among species with apomorphic traits (corollary being that marine habitats are favoured by the plesiomorphic members).
Lesser Antillean Polychaetes, chiefly from brackish water with a Survey and a Bibliography of Fresh and Brackish – Water Polychaetes
It looks as if the nereid type is the type which, of all the polychaete types, has the greatest power of adaptation to different circumstances and is therefore quite natural that the few genuine terrestrial polychaetes known as yet, and by far the greater number of fresh and brackish-water species, belong to the neReids.
Where did Marenzelleria spp. (Polychaeta: Spionidae) in Europe come from?
Genetic analysis by means of allozyme electrophoresis and sequencing of a segment of mitochondrial 16srDNA showed that two different genetic types or sibling species of Marenzelleria were present in Europe.
The Namanereidinae (Polychaeta: Nereididae). Part 2. Cladistic biogeography
Results indicate that the biogeographic patterns shown by species of both genera may be explained largely by vicariance, and are better explained by the expanding earth model which predicts that during the Jurassic Period the earth was substantially smaller, the Tethys Sea was much reduced (or absent) and the Pacific was essentially closed.
On the Caobangiidae, a new family of the Polychaeta, with a redescription of Caobangia billeti Giard
The type-species of CaobangiaGiard, C. billeti Giard, is redescribed, primarily in terms of its setal morphology, and a separate family, the Caobangsiidae, is erected for the genus.
The Freshwater co-occurrence of Eurytemora Affinis (Copepoda: Calanoida) and Manayunkia Speciosa (Annelida: Polychaeta): Possible relicts of a marine incursion
Evidence supports the theory that these animals may be relict forms resulting from the most recent marine incursion within the Ottawa River.
The life cycle of Ceratomyxa shasta, a myxosporean parasite of salmonids, requires a freshwater polychaete as an alternate host.
The actinosporean life stage of Ceratomyxa shasta, a myxozoan parasite of salmonids, and the annelid worm that serves as its alternate host were identified and their roles were confirmed using molecular techniques.
Re-evaluation of marine benthic species of nature conservation importance: a new perspective on certain ‘lagoonal specialists’ with particular emphasis on Alkmaria romijni Horst (Polychaeta: Ampharetidae)
It is concluded that it is probably still appropriate to maintain the protected status of A. romijni, but based on all UK records, the species should be considered ‘scarce’ rather than ‘rare’ using current assessment criteria.
Freshwater invertebrates of the Malaysian region
The freshwater fauna of tropical regions is poorly known, yet the tropics hold a large share of the world’s freshwater resources and some extreme and unusual habitats. This is the first publication
